* Prices are subject to change without notice due to fluctuations in the metals market. | All “Value Length” and “Value Pack” item measurements are subject to standard mill tolerances. | Products may be manufactured several thousandths of an inch over or under the stated dimensions and still be within acceptable mill tolerances. All bar, tube, structural, pipe, sheet, plate, and similar products sold on our website are custom cut to the lengths and sizes selected by the customer at the time of purchase. These are not stocked as pre-cut items. Because each order is cut specifically to customer specifications, all cut materials are considered custom products and are not eligible for cancellation, return, or exchange once production has begun. Our standard cutting tolerances are:

  • Length: +0.125″ / -0.062″
  • During the cutting process, the saw blade removes approximately 1/16″ (kerf) of material. This is a normal part of the manufacturing process and is already included within the stated cutting tolerances.
